When buying string trimmers or weed trimmers, we usually concentrate on the type of trimmer, whether it would be an electrical trimmer or gas powered trimmer.For domestic uses that consist of smaller lawns and gardens with matching driveways and sidewalks, it is obvious that the lightweight and almost noise-free electrical weed trimmers would do well. Battery operated trimmers whose main attraction is that it is cordless and adds more options to maneuverability are also quite a popular choice. Moreover, when the entire world is craving for greener alternatives, the electrical trimmers that do not emit any smoke or other pollutants are an excellent choice.

Gas operated weed trimmers are suitable for commercial use when large areas of land have to be kept tidy and dressed up in just a few hours. The high capacity and high-performance gas trimmers are very efficient, but it produces quite some noise along with harmful emissions. Since it is not possible to have anything better for dressing up larger areas, you may have to compromise on certain things.

However, there are some other essential considerations during selection besides what we have discussed so far. The trimmer head, which does the work of cutting weeds, is perhaps a critical factor that one has to consider during selection. It is also related to the efficiency of the equipment and the ease of operation and use. Do not forget to keep an eye on them during selection.

Bump Feed                                 

Bump Feed is the most popular line feed system use for weed trimmers. You can wound different lengths of the line on the spool of the trimmer. Two equal lengths of the line come out through the opening in the trimmer head. When you are using the trimmer, slight bumping of the head on the ground activates the spool that releases the spring system and advances the line through the line outlets that starts the trimming action. When you are using the trimmer, slight bumping of the head on the ground activates the spool that releases the spring system and advances the line through the line outlets that starts the trimming action Bump feeds are popular because it is easy to use and reliable as you have more control over the line during use. It is also easy to repair damages.

Automatic feed

If you come across a trimmer with automatic feed, you should know that it is a motorized version of bump feed systems. The principle of operation is the same as the bump feed system as it uses the line wound on a spool with the only exception that a spooling motor controls the action instead of doing it manually. It works on its own without having to tap or bump it thereby resulting in faster trimming.

Fixed head

In the fixed head system, you can load individual lengths of line into the trimmer, one at a time, according to your needs. This method does away with the trouble that you had to take for the winding line on to trimmer heads. The system simplifies the way of dealing with trimmer line, which becomes much less cumbersome. It is particularly popular for commercial use where it is necessary to use thick strings that are tougher.
